GAS HEATING-FURNACE.

' Application filed May 10, 1913. Serial No. 766,836.

T 0 all whom it may concern:

Be it known that I, FRANK BARLow SCHUYLER, residing at Berkeley, countyof Alameda, State of California, have invented certain new and usefulImprovements in Gas Heating-Furnaces, whereof the following is aspecification.

My invention relates to the art of heating for tempering variousarticles but for the purpose of this application I shall refer same asparticularly applicable to wagonsprings or the like, and has for itsobject to provide in this class of devices, new and useful means forgiving springs of either straight or curved forms the required degree ofheat without burning them.

WVith this object in view, my invention consists in a new and useful gasheating furnace, having a frame made of suitable material, as iron, withlegs suitably stayed and braced; a chamber supported on said legs inwhich are means for holding the springs and burners for directing heatagainst the surfaces of the springs; a separate compartment in saidchamber for warming springs; means for introducing mixed air and gasinto said burners including flexible and adjustably fixable pipes incombination with deflectable parts in said chamber for accommodatingcurved springs.

It also consists in the novel parts, combinations and arrangements setforth in the following description and as will be particularly pointedout in the appended claims, and illustrated in the accompanying twosheets of drawing, of which Figure 1, is a front elevation, partly inperspective and partly broken away of my new and improved gas heatingfurnace; Fig.

2, is an end elevation partly in section; Fig. 3, is a top plan viewwith a portion of the cover removed; Fig. 4, is a detail view enlargedpartly in section of the burner on one side of the spring, showing alsothe spring, holding means and means to regulate -the space between thespring and the burner; Fig. 5, is also a detailed view of my adjustableburner fixture, and Fig. 6, is also a detail plan view of part of theburners and a straight spring in position as it appears in the furnacefor actual practice, also showing in dotted line the position of theburners when the spring is of the curved form. The same symbol ofreference marks the same part in whichever view said part may appear.

Specification of Letters Patent PatentedNov. 14:, 1.91.6.

Referring now to the drawing, 1 is a frame of suitablematerialpreferably of angle ironhaving' legs2 braced as by the braces 3.On said frame a chamber 1 is supported having vent holes -5, air inlets6,

and a door 7 for inserting and withdrawing the springs. I The chamber isdivided into two compartments, A and B,- one above the other, the formerfor heating the springs, the latter for merely warming them. Supports 8for sustaining springs to be warmed are provided.

Within the compartment A, burners 9,10, and 11 are arranged on bothsides of the spring, the holes in which are staggered as at c, d, in Fig". 4L, in'which one of said holes is shown in full lines and one indotted lines, thereby showing that they are not in the same'verticalplane. There are also devices for holding the springs in positionwhichconsist in pins 12 extending through the floor of the furnace adapted tosecure the lower side edge of the spring 13, and adjustable bolts 14:supported on the burners enthe burner at proper distance from the springto be heated. Connected with said burners are devices for introducingmixed air and gas, consisting of pipe 15 for admitting air, the pipe 16for admitting gas, the mixing chamber 17, and the flexible pipes 18.

Thefiexible pipes are adjustably supported on the square rod 19 by thebracket 20, to which they are connected by the spring clips 21, thebracket being fixable in position on the rod by the screw 22. The rod 19is secured to a contiguous part of the frame of the apparatus. Theutility of the flexible pipes appears when it is desired to heat curvedsprings. In such case the burners are deflected toward the positionshown in dotted lines, Fig. 6, to accommodate the curve in the spring13.

Having thus described my invention and an adjusted position, a burnerfor heating said spring, bolts a'djustably mounted on said burnerengaging said spring and adapted to regulate the space therebetween.

2. In a heating device of the character described, removable pins forholding material to be heated, a vertically and horizontally adjustableburner provided with bolts adjustably secured thereon and projectingtherefrom engaging said material and adapted to regulate uniformly thespace between said material and the burner,

3. In a device for heating vehicle springs, a base, a chamber mounted onsaid base, means in said chamber for holding said springs in an adjustedposition, a burner for heating said springs and adjustable means on saidburner engagin said springs adapted to regulate the space between saidsprings and burner.

l. In a device of the character described, a furnace comprising a frame,a. tWo vertically disposed compartment chamber supported thereby, one ofsaid compartments provided With removable bars adapted to supportsprings for preliminarily Warming and the other adapted for heating thesprings, said latter compartment provided With adjustable burnersarranged to project heat on both sides of said springs, adjustable meansfor supporting said springs on their side edges, and means forintroducing mixed air and gas to said burners.

5. A gas heating device comprising a frame, a chamber supported therebyhaving a loWer and an upper vertically disposed compartment, removablemeans in said upper compartment for supporting springs to be warmed, andadjustable burners in the lower compartment for heating said springs,and means for introducing mixed air and gas into said burners.

In testimony that I claim the foregoing I have hereto set my hand in thepresence of Witnesses, this fifth day of May, 1913.
